Question 2 A driven harmonic oscillator of mass m = 0.4 kg has the equation of motion 0.40* + 0.20* +0.275x = 0.079 cos(0.750t) N. (a) Verify that the system is in amplitude resonance and calculate the steady state amplitude A. (b) Verify that if the driving force were removed, the system would be underdamped. (c) How long would it then take for the oscillation amplitude to decrease to 5 mm?
